Explanation of Solution
Ways to measure the success of customer satisfaction:
In a business model, it is very important to analyze the data. It is impossible to measure the success of customer satisfaction without using any metrics. Customer service metrics include:
- Cases that has been closed the same day:
- The issues regarding the automobile should be observed and resolved as early as possible.
- Number of the cases that are handled by agent:
- Some issues are handled by agents that should be known so that the risk of hampering the company’s reputation can be avoided.
- Number of service calls:
- The number of services calls should be recorded and the issues should be taken care.
- Average number of service requests by type:
- There are many types of service requests and each one is dealt in its own way...

Question D.4: FIFO Page Replacement
Consider the following page reference string:
e, c, b, e, a, g, d, c, e, g, d, a
Considering 4 frames, fill in the following table and then answer how many page faults would occur with the
FIFO page replacement algorithm.
RS: reference string; FO: frame 0, F1: frame 1, etc.
Hint: all frames are initially empty, so your first unique pages will all cost one fault each.

Consider a system that uses a fixed-partition scheme, with equal partitions of size 2" bytes, and the main
memory has 2¹8 bytes. A process table is maintained with a pointer to the resident partition for each resident
process. How many bits are required for the pointer in the process table? Show all your steps.

Re-write the withdraw() method in the CheckingAccount class so that it first checks if the withdrawal amount is less than the current balance plus the overdraft limit. If it is, the withdrawal is allowed and the balance is updated. If not, the method should return an error message "Insufficient funds".
